Dear Alibaba Cloud users
To provide better services, starting from 00:00:00 (UTC+8) on June 30, 2025, CloudMonitor upgrades the monitoring capabilities for Dynamic Content Delivery Network (DCDN).
Upgrade description
CloudMonitor will replace the DCDN HTTP data source with a new data source that has lower latency. Because the old data source had a reporting logic for 0 value BPS and QPS, these 0 values might be ignored in the new data source. If you have configured alerts for 0 values of BPS (metrics: bps_out_http and bps_in_http) and QPS (metric: dcdn_qps_http), you can adjust them to No Data alerts to prevent impacts on your business.
We apologize for any inconvenience caused. If you have any questions, you can contact us at any time by submitting a ticket.
